• Building ffmpeg example, trouble linking

  16 octobre 2022, par Expressingx

  I want to debug ffmpeg example, transcoding

  


  I've followed the compilation guide for ubuntu and everything is fine. Now I want to do some changes (e.g. opening actual camera) and had to add avdevice_register_all() function. Because of that now I cannot build it. The command for building is

  


  /usr/bin/gcc -fdiagnostics-color=always -g /home/myuser/ffmpeg_sources/ffmpeg/doc/examples/transcoding.c -L/home/myuser/ffmpeg_build/lib -I/home/myuser/ffmpeg_build/include -o /home/myuser/ffmpeg_sources/ffmpeg/doc/examples/transcoding -lX11 -lXext -lxcb-shm -lavdevice -lavformat -lavfilter -lavcodec -lswresample -lswscale -lavutil -lm -lx264 -lgnutls -lfdk-aac -lvdpau -lva -lz -lpostproc -lva-x11 -lva-drm -lxcb -lxcb-shape -lxcb-xfixes -lxcb-render -lasound -lsndio -lSDL2 -ldl -lbz2


  


  but I get one error

  


  /usr/bin/ld: /home/myuser/ffmpeg_build/lib/libavdevice.a(xv.o): undefined reference to symbol 'XGetWindowAttributes'
/usr/bin/ld: /usr/lib/gcc/x86_64-linux-gnu/12/../../../x86_64-linux-gnu/libX11.so: error adding symbols: DSO missing from command line


  


  What am I missing ?

  avformat/mpegts : use buffer pools for allocating PES payloads
  This brings a performance improvement when demuxing files, most of the
  
  improvement comes from buffer pooling unbound packets.
